IMPROVEMENTIN cARBu|=aEr|aRs-v Specification forming part of LettersPatent No. l 68,797. dated October `11, 1875 application filed f iOctober 5, 1875.

To all whom it may concern l Be it known than, WILLIAM D. SNOW, 0f-Brooklyn, in the countyV of Kings and State of New York, have inventedcertain new and usefullmprovements in Carbureters, of which thefollowing is a specification:

This invention relates to certain new and useful improvements inapparatus for carburetlng air or gas, its object being to provide aconvenient and ready means for inserting the endanger the apparatus andsurrounding objects.

My invention consists vin a cylindrical, po-V lygonal, or other shapedvessel, provided with inlet-pipes for filling in the carburetiugfluidand for the admission of air or gas, and an exit-pipe leading to theburners for the escape of the carbureted air or gas, and containing avessel or basket of wiregauze or other suitable foraminous material,contracted or conically-shaped toward the bottom, and provided with aseries of horizontal partitions of wire-gauze or equivalent foraminousmaterial, the spaces between which are illed with a packing of sponge orother brous material, as hereinafter more fully set forth and described.

The drawing represents a vertical sectional view of my improvedapparatus for carbureting gas orv air. The letter A represents an outercasing of metal or other suitable material, of a cylindrical, polygonal,or other suitable shape, and provided with the pipes B and C, the pipe Bfor the admission of air or gas to becarbureted, and the pipe O for theescape of the carbureted air or gas on its way to the burners. Saidpipes are provided with stop-cocks b and c, to control the ow of the` edwith the uncarbureted air or gas to any desired extent, if too richlycarbureted.' The letter E represents a basket or basket-shaped vessel ofwire-gauze or other foraminous material, provided with a series ofwire-gauze or other foraminous horizontal partitions, c. The lower partof said basket is contracted, as shown, so as to leave an annular clearspace around the bottom of the vessel A, for the collection of thehydrocarbon fluid employed for carbureting the air or gas. The spacesbetween the partitions are filled or packed with any suitable fibrousmaterial, preferably with cut sponge, to absorb the carburetingliquid,and present an extended surface of the same to the action of the air orgas to be carbureted.

The carbureting-vessel is provided at any convenient point with anaperture or pipe for filling in the hydrocarbon liquid, and a suitableoutlet at or near the bottom for drawing oi' any residue, when desired.

The operation of my invention will be readiv ly understood from theforegoing description. The spaces in the basket are properly lled withthe sponge or other fibrous material and the basket placed in the vesselA, which is securely closed. The vessel A is then charged lwith thehydrocarbon liquid, consisting, as

usual, of the lighter varieties of naphtha, or the volatile constituentsof petroleum. Thiswill be absorbed or taken up by the capillaryattraction of the sponge, which will expose an extendedevaporating-surface to "the action of the air or gas which is let inthrough the pipe B, thoroughly carbureting the same. Any surplushydrocarbon collects in the annular space around the bottom of thebasket, and, as the absorbed hydrocarbon is carried'off from the spongeby the air or gas, the surplus hydrocarbon is carried up by thecapillary attraction, thus insuring the effective operation of themachine until the hydrocarbon liquid is entirely exhausted.

As thus constructed, an extremely simple, effective, andsafe apparatusis produced, in which the packing can be readily and convenientlyinserted and supported in such manner as to prevent the matting orsettling oi' the same, which would interfere with the effective workingof the machine.

principle 'of the Davy safety-lamp, Will effect' ually prevent anycommunication of re to the apparatus, and thus insure perfect safety inits use.

The carbureters, as thus constructed, can be lIill'ed and transportedfrom place to place with perfect safety, asthe bulk of the hydrocarbonis absorbed by the sponge, and in case of carelessness in properlysecuring the openings of the same, or of accidental breaks, very little,if any, of the liquid can escape, to en danger surrounding objects.This, it Will be seen, is an important advantage in innumerableinstances, When portable carbureters are required.

Having thus described my invention, what I claim, and desireto secure byLetters Patent, 1s-

In an apparatus for carbureting air or gas, the combination, with thecarbureting-vessel A, of the foraminous or wire-gauze basket E, providedWith horizontal foraminous partitions for supporting the packing, andnarrowed toward the bottom, so as to leave an annular space for thehydrocarbon liquid, the upper part being of such size as to ill ornearly fill the gas-chamber of the vessel A and prevent the collectionof explosive gases, substantially as described'.

In testimony that I claim the foregoing, I have hereunto set my hand inthe presence of the subscribing Witnesses.

W. D, SNOW.
